test example

What steps will reproduce the problem?
(1) Define a @font-face with a variable font
(2) Add a font-variation-settings rule to that @font-face
(3) Use the font

What is the expected result?
font-variation-settings are applied to font

What happens instead?
font-variation-settings are not applied to font

Please provide any additional information below. Attach a screenshot if possible.

CSS Fonts module level 4 says:

https://drafts.csswg.org/css-fonts-4/#font-rend-desc

"These descriptors [font-feature-settings, font-variation-settings; my comment] define initial settings that apply when the font defined by an @font-face rule is rendered."

(font-variation-settings DO work in Safari)

Without this working, it is much more complicated and verbose to add a fallback for non-variable fonts when using `font-stretch`.
